My wifi asks for me to sign in on Android?

[JoQ]

I have been using Merlin software for my AC68U for years and always been very happy with it. But for some reason when I got an Android-phone I sometimes loose internet-connection and get a Wifi-symbol with a question-mark over it. And it asks me to sign in to the wifi. Clicking this notification opens a webbrowser and a blank page which disappears after a few seconds and then internet is back in business.

This only happens on my Android-phone. Have not noticed it before this.

What's the reason for this?

That's a problem with your Android phone.

Try "forgetting " the WiFi connection on the phone and set it up again.
